CORN-CUTTING DEVICE.

Application filed July 23,

7 '0 all whom it may concern.

Be it known that I, DAVID E. RYDER, a resident of the city of Newburgh, N. Y.. citizen of the United States, residing at Newburgh, in the county of Orange and State of New York, have invented certain new and useful Improvements in Corn-Gutting Devices; and I do hereby declare the following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

The object of this invention is to provide a novel construction of device for cutting corn from the cob which is simple in construction and thoroughly efiicient'in operation.

A "further object is to provide, in connection with this cutting device, means for collecting and guiding the corn after being cut from the cob, to a suitable place of deposit. 1

A further object is to provide novel means, in connection with the cutting device, for forcing the corn cob against the knife.

A final object is to provide the unitary structure comprising the cutting device, the means for guiding the cut corn, and the means for forcing the cob against the knife,

with suitable means for supporting the same from an object, such as a table or the like.

The invention is fully described in the accompanying drawings, illustrating the preferred form thereof. Briefly described: 1

Figure 1 is a central vertical sectional view of my device, parts thereof being shown in elevation;

Fig. 2 is a detached detail view, inside elevation, partly broken away, of the inside. cylinder; a

Fig. 3 is'a horizontal sectional view on. the line 33 of Fig. 2, looking in the direction of the arrows; and

Fig. 4 is a horizontal sectional view on the line 4-4 of Fig. 1, looking in the direc tion of the arrows.

Referring now in detail to the drawings:

1 designates a hollow member, open at both ends, and preferably formed truncated cone-shaped.

Suitable means are provided for supporting the cylinder in a vertical position with Specification of Letters Patent.

1920. Serial No. 393,343.

respect to a table, or the like, and in this instance, said means comprise a bracket 3 having parallel armsiand 5,the former being adapted to bear upon the top of a table, or the like, and a screw-clamping member e threaded through the lower arm 5 and adapted to bear against the under surface of the table, thereby firmly frictionally holding the cylinder 1 against accidental displacement.

Disposedin said cylinder 1 is a Second split cylinder 7, preferably shorter in length than the outside cylinder 1 and also openended, and provided with overlapping edges 8, 8. Said inner cylinder 7 is formed of portion '8 carries a rivet 9, passing through a slot 10 in the inner overlapping portion 8;

Suitable means for supporting said inner cylinder in position, with reference to the outer cylinder 1, may be provided, and in this instance said means comprise a plurality of brackets 10, projecting interiorly from the inner face of the cylinder 1, pins 11, carried by the inner cylinder 7 and projecting outward therefrom, being adapted to rest upon said brackets 10, as clearly shown in Figs. 1 and 4. Said brackets 10 are preferably,trough-shaped, as shown in Fig. 4.

The upper marginal edge of the inner cylinder 7 is sharpened at 12 to form a knife edge, constituting the cutting portion of the device.

Interposed between the inner cylinder 7 and the outer cylinder 1, is a plurality of coiled springs 13 preferably situated toward the top of the cylinder 7.

An inclined runway or gravity slide 14 is disposed inside the cylinder 1, and the cylinder 7 projects through said slide, as clearly shown in Fig. 1. Said slide projects through an opening 15 in the wall of the cylinder 1 and terminates in a chute 16 projecting exteriorly of the cylinder 1 as shown in Fig. 1.

Suitable means is provided for positively forcing the ear of corn downward through the cylinder 7, the knife portion 12 of said cylinder successively cutting off circumferential layers of the corn as the ear of corn is forced downward through said cylinder, the severed corn falling into the gravity slide 14 and thence passing into the chute 16, the top of which may be disposed above a receptacle disposed upon a table, to which the device is clamped. Said means for forcing the ear of corn downward preferably comprise a gripping member 17,in this instance a hemispherical body provided on its lower edge with teeth 18. Said member 17' is carried on the lower end of a rod 19, depending from and preferably secured at its upper end, as shown at 2-0, to a lever 21, fulcrumed at 22 at the top of a bracket 23 secured, toward its lower end, as shown at 2%, to the top of the cylinder 1.

In operation, an ear of corn is placed with the smaller end thereof in contact with the knifeportion 12 of the truncated coneshaped cylinder 7, with the gripping member 1'? bearing against'the upper end of said ear; whereupon the lever 21 is forced downward, thus driving the ear of corn into the cylinder 7, the knife portion '12 slicing off the kernels of corn which fall downward into the gravity slide 1 as before stated. As the ear of corn is forced downward, as described, the cylinder 7 is expanded against the pressure of the springs 13, the rivet 9 preventing the overlapping portions 8, 8 from beingforced away of the cylinder. Then the ear of corn falls from the bottom of the cylinder. 7 the resiliency of the spring material, of which .the cylinder is composed, assisted by the coiled springs 13, returns the cylinder 7 to its normal contracted position. It is to be noted, of course, that while there'siliency of from each other, and-also limiting the degree of expansion the spring material may be depended upon to its normal conto return the cylinder tracted position'and after expansion thereof, I prefer to supplement the resiliency by the action of the coiled springs 18.

-What I claim to be new is: 1. A corn cutter comprising an expansible tubular sleeve having overlapping edges with its side walls converging upwardly to a cutting annulus, a housing surrounding the sleeve, and means to force a cob longitudinally through the sleeve.

2. A corn cutter comprising an exp'ansible tubular sleeve having overlapping edges with its side walls converging upwardly to a cutting annulus, a housing surrounding the sleeve, means to force a cob longitudinally through the sleeve, and a chute positioned at an inclination within the housing and embracing the sleeve. 1

8. A corn cutter comprising an expansible tubular sleeve having overlapping edges with its side walls converging upwardly to a cutting annulus, a housing surrounding the sleeve, means to force a cob longitudif na'lly' through the sleeve, and a chute extending at an inclination within and .withoutthe housing and embracingfthe sleeve in position j to receive material falling about the exterior thereof.

v In testimony whereof I hereunto affix my signature. 1
